With access to bikes and parts from all of the major OEMs, Josh can race any 450 he wishes, but the selection process this year has come down to two. In the past, he has ridden different bikes at each round, but this year we&#8217;re looking for one consistent steed to ride for three planned events. Cameron Purcynski joined for the day to offer his advice and input after watching Josh on both bikes.
